browser-automation
Playwright-based browser automation for reliable web testing, scraping, and agent interactions.
- Emphasizes user-facing locators and Playwright's auto-wait mechanism to eliminate flaky selectors and arbitrary timeouts
- Enforces test isolation patterns with fresh state per test and stealth plugins to avoid detection systems
- Covers anti-patterns including CSS/XPath-first selection, single browser contexts, and manual wait calls
- Includes sharp-edge guidance on traces, viewport consistency, request delays, and popup timing to prevent common failures
Browser Automation
Browser automation powers web testing, scraping, and AI agent interactions. The difference between a flaky script and a reliable system comes down to understanding selectors, waiting strategies, and anti-detection patterns.
This skill covers Playwright (recommended) and Puppeteer, with patterns for testing, scraping, and agentic browser control. Key insight: Playwright won the framework war. Unless you need Puppeteer's stealth ecosystem or are Chrome-only, Playwright is the better choice in 2025.
Critical distinction: Testing automation (predictable apps you control) vs scraping/agent automation (unpredictable sites that fight back). Different problems, different solutions.
Principles
- Use user-facing locators (getByRole, getByText) over CSS/XPath
- Never add manual waits - Playwright's auto-wait handles it
